STARTING MECHANISM FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 419,423, dated January14, 1890.

Application filed March 3, 1888. Serial No. 266,080. (No model.) H

To all whom it may concern.-

Be it known that 1, JOHN STENGER DAVIS, a citizen of the United States,residing at T0- ledo, in the county of Lucas, State of Ohio, haveinvented certain new and useful Improvements in Starting Mechanism forGrain- Binders, of which the following isa description.

My invention relates to grain-binders of the class generally known aslow-down or platform binders, in which the grain is bound by mechanismlocated on or substantially on the level of the platform, into thegave-ling and binding receptacle of which it is delivered by a suitableplatform-carrier.

lVhile this present improvement is particularly applicable to thespecial type of machines shown and described in the many patents ongrain-binders granted to me since 1581, some portions of it may byslight. modification be adapted to use in other machines withoutdeparting from the spirit of my invention, as hereinafter fully setforth and claimed.

The objects of my invention are to cut off the flow of grain into thebinding-receptacle by means of a series of fingers projecting into themoving'stream on the platform at a predetermined time before thestarting of the binder, to start the cutoff-actuating mechanism by atrip actuated-bythe pressure of the grain in the binding-receptacle, tostop the cut-off mechanism and hold its'fingers in the path of theincoming grain, restraining and holding it out of reach of thegavel-packing devices during the bindingoperation, to cause the cut-offmechanism at or near the completion-of its first movement to start thebinder,

to lift and hold out of engagement during the binding operation thetripping device by which the cut-off mechanism was first started, tocause the binder before the completion of its movement to retrip thecut-off mechanism which retracts the fingers and allows the obstructedgrain to flow into the binding-receptacle, to positively stop the binderat the end of its movement and hold it against accidental rotation, tosuch an arrangement of the gearing as will insure the timely trippingand proper engagement of the binder-starting device with itsactuating-pinion, and to the details of construction by which theseprincipal as well as other objects of minor import are carried intoeffect.

In the accompanying drawings, Figure 1 is a plan view of so much of agrain-binding harvester as is necessary to illustrate the application ofmy improvements thereto. Fig. 2 is a front elevation showing themechanism in its normal position of rest and someof the parts brokenaway for the purpose of more clearly illustrating those behind them.Fig. 3 is a rear elevation, partly in section, on the lines 3 3 of Figs.1 and 5, also showing the mechanism at rest. Fig. 4. is a similarelevation,partlyin section,on the line 44of Fig. 1. Only a small portionof the gear-plate, upon which the moving mechanism is mounted, is shownin this figure, the remainder being omitted to secure clearness ofillustration. The mechanism is shown in the position as sumed at adifferent stage of the operation from that illustrated in the precedingfigures. .Fig. 5 is an outside elevation, partly in irregular section,on the line 5 5 of Fig.3. Fig. 6'

is a plan view of the spring-dog that locks the main binder wheelagainst accidental rotation. Fig. 7 is a detached view, in front ele-Evation, of the cut-off cam-wheel and its trip-- ping mechanism. Fig. 8is a section through the same on the line 88 of Figs. 3and 7. Fig. 9 isa horizontal section through the main binder-wheel on the line 9 9 ofFig. 4. Fig. 10 is a plan View of the slide-plate which starts and stopsthe binder, detached. 11 is a sectional view on the line 11 11 of Fig.l4. of the cut-off bell-crank lever, detached. Fig. l2'is a sectionalview taken on the line ?12 12 of Fig; 3..

The supporting-frame upon which my present binder is mounted resemblesmore or less close1y those shown in the several patents onEgrain-binding harvesters granted to me since .1881, while specialreference might be made to my patents numbered 274,444 and 311,420,.dated March 20, 1883, and January 27, 1885, respectively, to which thismy present invention is closely allied in the objects it is sought toaccomplish.

A As in my former inventions, the binderframe sill-bars A A extendacross the outer end of the platform, resting upon and secured Fig.

to the angle-iron finger-beam A in any suit able manner, and, projectingforward in ad vance of the finger-beam, are provided with upturned frontends, as shown. Upon the sills, between the finger-beam and theirupturned ends, is mounted the binder-plate B, suitably shaped, as shownin the drawings, to afford supports for the moving parts of themechanism, and provided with feet I), by means of which it is securelybolted to the sill-bars. From the front upturned end of the sill-bar A abrace-rod a extends to the top of the binder-plate, to which it issecurely and ad justably clamped by screw-nuts, as shown. An uprightpost or bar A is bolted to the front upturned portion of the sill-bar A,as shown, and secured to it at a suitable height above the bindingmechanism is a rearwardly-extending rail-bar A, which is suitablysupported at its rear end (not shown in the drawings) and carries oneend of the breast-bars O '3', which constitute the top of thebinding-receptacle. The other ends of the breast-bars are attached to arearwardlyextending rail-bar A which is bolted at its front end to thetop of the binder-plate, as shown. The bottom of the binding-recepta cleis composed of spring fingers or bars D, securely bolted to the innersill-bars A and extending above and beyond the outer sillbar, asillustrated in Figs. 1 and 3.

The platform-carrier consists of a series of narrow belts E, which passthrough the spaces between the spring-fingers D to the drivingroller E,located beneath the binding-receptacle, and deposit the grain which theybring in from the platform upon these fingers within reach of packingdevices mounted upon the continuouslyrotatin g packer-shafts F. Thesepackers may be of any suitable kind; but I prefer to use packers likethose illustrated in my patents, No.283,86(3, August 28, 1883, and No.388,642, August 28, 1888. The packershaft is driven continuously fromthe main actuating-shaft E by means of the wheels and pinions e, e, G,and F, the former being attached to the shaft E and the latter to thepacker-shaft F, while the intermediate wheels 6 G revolve on stud-axlesprojecting from the front face of the binder-plate B. The mainbinder-gear l-l meshes into and is actuated at intervals by the pinionG, as will be hereinafter described.

The main purpose of this invention, like that of my patent of I March20, 1883, No. 274,441,is to effect a wide separation of the bundle thatisbeing bound in the receptacle from the incoming grain on the platform,and to accomplish this I locate on the platform below the surface of thecarrier-belts a series of cutoff fingers, which, when raised, intersectand stop the incoming grain at a point on the platform out of reach ofthe packing devices. These fingers are raised and the inflow of grainchecked for a sulficient period before the binding mechanism is startedto permit the packing devices to clear up and urge into the receptacleall the grain which has passed the cut-off fingers before they areraised, the fingers being held in their upright position, opposing theentrance of more grain into the receptacle until the completion of thebinding operation. The mechanism by which this cut-off is actuated hastwo distinct movements: It is first tripped and started by a lever orfloat I (depending into the bindingreceptacle and lifted by the pressureof the gavel packed therein) and makes a half-revolution, during whichit raises the cut-off arms on the platform and holds them in oppositionto the incoming grain, disconnects or throws out of operation themechanism through which it was tripped by the float, and before thetermination of its movement trips the binding mechanism into action. Itthen comes to rest and holds the cut-off arms up until the completion ofthe binding operation, when it is again tripped into action by the finalmovement of the binder and returns to its normal position of rest,lowering the cut-off arms below the plane of the carrierbelts andrestoring the float-tripping mechanism to its activeposition.

The constantly-revolving packer-shaft F, mounted in bearing 1) on thebinder-plate, has keyed upon it, in close proximity to said plate, aratchet-wheel F. A cam plate or disk J is loosely mounted upon thisshaft adjacent to the ratchet-wheel Fibetween which and a crosspin andwasher F on the shaft it is held from endwise movement thereon. Pivotedupon the front face of this disk is a hooked latch-piece f, which, whenreleased, engages the ratchet F and compels rotation of the disk Jtherewith. A spring f, which urges the latch into engagement with theratchet, is located on the rear side of the disk, and acts upon a stud fprojecting from the rear side of the latch through a slot in the diskand perforated to slip over a pin f which guides the sprin The latch hasa long tail or extension which terminates in a hook or catch f, and isguided by a pin f fixed to the disk and playing in a slot, curvedconcentrically with the pivot of the latch. At a point near the pivotthe dog is also provided with another catch-hook f at the end of anincline f on its outer side. These hooks f f are alternately caught andthe latch drawn out of engagement with the ratchet-wheel F by a dog K,pivoted between IIO suitable lugs on the binder gear-plate B, and

float consists of a bar loosely pivoted upon the packer-shaft F anddepending into the receptacle below the breast-bars O G, as shown inFigs. 1, 3, and 5.

Loosely pivoted in a bracket formed by lugs c a, rising from one of thebreast-bars 0' above the receptacle, is a bell-crank lever I, the longarm of which extends horizontally to a point above the float and isconnected thereto by a link 2', the point of connection being madeadjustable by means of a crosspin 2", taking into a series of holes inthe upper end of the link to permit of variation in the sizes of thegavels to be accumulated be fore the mechanism is tripped. A spring 2'on the sleeved shank of the bell-crank normally acts to hold the crankin the position shown, and its stress must be acted against when thefloat is being raised by the pressure of the gavel. The short arm of thebellcrank is connected to a sliding link or thrustbar 1 which has at itsfrontend a project- 'ing finger i which rests upon the top of theprojection is of the trip-dog K, and an abrupt shoulder 11, which bearsagainst said projection when the link is thrust forward and swings thedog upon its pivot, carrying its hooked projection 70 out of the path ofthe latch f, releasing and allowing it to engage the ratchet F and startthe cut-off mechanism on its first movement.

As will be readily understood, the packing of the gavel into thereceptacle will, when sufficient grain has been accumulated, raise thefree end of the float, rock the bell-crank lever on its'pivot, and movethe push-bar which rocks the trip-dog and hold said pushbar forwarduntil the gavel is bound and ejected from the receptacle. The firstmovement of the cut-off mechanism consists of but a half-revolution ofthe cam-plate, and its latch f at the completion of this first movementmust be disconnected from the ratchet by the trip-dog K. In order torelease this dog from the float-tripping mechanism by which it was firstpushed out of engagement with the latch f, that it may swing back andre-engage with the latch by its hooked extremity f I support the frontor free end of the push-bar I in an aperture or suitable guideway Z on abar L, pivoted at Z to the binder-plate and trailing at its free end ona cam L on the cam-disk J. When the disk J is connected to the ratchet Fby its latch and begins to revolve, this cam L raises the free end ofthe barL, which in turn raises the end of the push-bar F and lifts itabove and out of contact with the projection is on the trip-dog, freeingthe latter and permitting its hooked end 70 to swing back into the pathof the latch f, which it engages with at the completion of thehalf-revolution of the cam and draws it out of engagement with theratchet. When the dog K first trips thelatch f, it does so by riding orsliding upon the inclined surface f forcing that portion of the latch intoward the ratchet-wheel and raising its catch-hook out of the teeththereon. The hook f P merely serves as a dead lock or stop to preventthe cam-plate from overrunning its desired position through the momentumacquired by its movement.

.hook.

The main binder-wheel H and the mechanism which it actuates are trippedinto action by the cut-off mechanism, in a manner'that will hereinafterbe fully described. On the rear face of this binder-wheel is a cam ledgeor projection h, having a sharp rise h, which,

shortlybefore the completion of the revolution of the wheel, acts uponan anti-friction roller k mounted upon the end of an arm or rigid stud kprojecting from the stop-dog K, swinging it sidewise and throwing itshooked end 10 out of engagement with the latch f, which is permitted toagain engage with the ratchetwheel and carry the cam J through its finalhalf-revolution. The cam-ledge terminates abruptly, as shown at h inFigs. 5 and 9, and permits the trip-dog K to fall back into the path ofthe latch f in. time to ride upon its incline f and again pull .it outof engagement with the ratchet and into the position shown in Figs. '2,7, and 9, which is the final position of rest. The cut-oft fingers M aremounted upon a rock-shaft M, which extends across the platform fromfront to rear and is journaled in suitable bearings. These fingers liein'the spaces between the belts, and when down, as shown by full linesin Figs. 1 and 3, are entirely below the plane of their top surface. Acrank arm or lever M at the front end of the rock-shaft is connected bya link M to one arm of a bell-crank lever M pivoted at M on thebinder-frame. The other arm of this lever carries an anti-frictionstudroller M, which takes into a cam-groove on the face of the disk J.In the position shown in Fig. 3 this roller lies in that part 'm of thecam-track nearest the aXis of the shaft F; but at the commencement ofthe movement of the cut-off mechanism it is moved away from the shaftbythe quickly-rising portion m of the cam-track. From this point thecam-track is concentric to the point m and holds the bellcrank roller inits position most remote from the shaft, which it continues to dothroughout the first movement, the result of which is that the cut-offarms are thrown up into the position shown by dotted lines in Fig. 3,and full lines in Fig. 4, as soon as the machine is tripped, and areheld in this position until the completion of the binding operation.

The construction of the bell-crank lever M and the stud-pin h upon whichit is pivoted, is shown in Fig. 11. The shank m of the stud-pin passesthrough the binder-plate and is secured by a nut at its end. Thestrengthening brace or rib m on the bell-crank con- IIO tacts with astop-lug m on the binder-plate when the cut-off arms are elevated, andprevents the roller M from accidentally passing out of the cam-track atthe opening p" placed therein, for a purpose to be hereinafterexplained. As before stated, the cut-oif arms are thrown up to theirelevated position at a predetermined time before the binding mechanismis tripped into action by the cut-ofl mechanism in its first movement.The means by which this is accomplished'I will now'describe. The bindergear-wheel II, when revolved, is engaged by the pinion G, as beforestated; but when the binder mechanism is in its position of rest thispinion, which is constantly revolving, moves in a space formed by theomission of three of the teeth from the periphery of the binder-wheel. Asliding bolt H, suitably housed by a casing on the outer face of thewheel, has a tooth formed at its outer end, which, when projected fromthe casing, extends into the path of the two side projecting teeth 9 gon the pinion and compels rotation of the binder gear-wheel far enoughto bring its fixed teeth into mesh with those of the pinion. At itsinner end this bolt is provided with a stud-pin H which proj ectsthrough a slot 71.3 in the face of the wheel and into the path of camsprojecting from the inner face of a sliding bar N. (Fully shown indetail in Figs. 1, 2, 3, 4, 5, and 10.) This bar is housed in a suitableguideway 13 formed in the binder-frame and held therein by a strap orplate I) at its outer end, and is slotted, as shown, to embrace the bossB, extending from the gear-plate, in which is fastened the stud-axle Bof the main wheel. EX- tending forward from its front face are twocam-ledges n a, between which the stud H projecting from the slidingbolt, is embraced when the binding mechanism is at rest, and by means ofwhich the bolt may be drawn forward to engage the pinion or held backout of its path, as determined by the position of the bar N. At itsinner end the bar is connected to the upper end of a swinging arm 0,pivoted at O on the binder-frame and urged to its retracted position, asshown by full lines in Fig. &, by a spring wound about its hub andengaging pins on the arm and binderframe, as shown in the drawings. Anantifriction roller 0 is mounted upon the pivotpin 71 which connects itto the sliding bar N, and bears, when the machine is at rest, against aperipheral ledge P on the cam-plate J, which ledge holds the bar forwardagainst the stress of the spring 0 as in the positions shown by fulllines in Fig. 3. At the termination of the first movement of the cut-offmechanism the roller, which has been bearing against the concentricflange P, runs off its point p, and the bar is retracted by the spring 0to the position shown in full lines in Fig. 4, projecting the bolt 11'into the path of the teeth of the pinion G. To prevent mishap in theevent of the breakage or failure to work of the spring 0 I provide aneccentric camledge P on the cam-disk J, which passes outside of theroller 0 at the end of the sliding bar and positively retracts it to theposition shown in Fig. 4. This ledge is eccentric from its point p to 13and concentric from there to its end 17 and is not so high as theconcentric ledge P, which holds the sliding bar forward. On the finalmovement of the cutoffmechanism the end p of the ledge P contacts withthe end a of the sliding bar N, and shoves it forward to such a positionthat when the stud II of the sliding bolt passes between its twoprojecting cams n n it will be withdrawn into its casing and out of thepath of the pinion G. At the same time the antifriction roller 0 passesout of the opening 1), between the points p and p of the ledges, andrides against the outer side of the ledge P, as before described.

In Fig. 4 the parts are shown in the positions they assume at the momentthe cut-off mechanism has completed its first movement and come to restuntil the completion of the binding operation. The sliding plate N hasbeen drawn in by the action of the spring 0 or the eccentric ledge P, orboth, and the sliding tooth II projected into the path of one of theextension-teeth on the pinion G, by which it will presently be engagedand the binder put into operation.

Immediately after starting the binder-wheel the stud II passes frombetween the ledges n n, and the bolt 1-1 is then free to slip back andforth, being limited in its movement by the length of the slot 7L3.Before the completion of the revolution of the binder-wheel it trips thecut-off mechanism into its second actuation, as before described, andthis almost instantly moves the sliding plate N from the position shownin Fig. 4 back to the starting position shownin Figs. 2 and 3. It willbe observed that the cam-ledge n on the bolt is concentric with the axisof the Wheel when the bar is pushed back, and that the ledge 11.

is eccentric, as shown, to present a wide opening at between them forthe entrance of the stud I1 When the wheel H has been revolved to apoint that brings the bolt 11' above its axis, if the bolt is loose inits housing it will drop by gravity until the stud II falls upon thecam-ledge n and follows it around to the position shown in Figs. 2, 3,and 9; but if too tightly fitted to move in this way it will bepositively drawn back by its sliding contact with cam-ledge n.

In order to abruptly check the forward rotation of the wheel H at thecompletion of its movement, I form upon its rear face a projecting ledgeor stop-lug h, which strikes against a lug n projecting from the bar Nwhen the latter is in its normal position, as shown in Figs. 2, 3, and5. When, however, the bar is moved to the position shown in Fig. at tothrow the bolt II and start the binder, the lug a is moved out of thepath of the lug h on the wheel, leaving it free to revolve. In order toprevent accidental rotation,

through jarring or otherwise, the moment the wheel is unlocked, and alsoto prevent backlash or rebound when the wheel is suddenly checked in itsrotation, I employ a yielding stop. (Shown in detail in Figs. 1, 2, 3,and at.)

A ledge H at the side of the teeth on the wheel projects above theirendsand isnotched or indented at h? to receive an anti-friction roller R onthe end of a dog R, pivoted at r on the binder-frame by means of thestay-bolt a and a spacing-thimble r as shown. A studpin projecting fromthe front of the dog is borne upon by a spring S, fastened to the frame,while a stop-lug r strikes upon the top of the frame and limits thedownward movement of the dog. The roller R takes far enough into thenotch to insure a firm hold on the wheel and prevent accidentalrotation, but not enough to restrain it from being positively actuatedwhen thrown into gear with the pinion G. e

The pivot of the swinging arm 0 is coincident with the aXis of thepinion e, and they are mounted as shown in Fig. 12. Upon one side of theframe is a spacing-thimble e and an end washer for the reception of thepinion 6, while upon the other side of the frame is aspacing-thimble 0,upon which is mounted the arm 0, as shown, a single bolt 0 passingthrough both thimbles and the frame, clamping them firmly together.

In order to guard against throwing the sliding bolt II forward intoaction. at a time when its end would strike the end of one of the teethg on the driving-pinion G, I arrange the gearing and ratchet-wheel F asfollows: The pinion G has an even number of teeth-- in this instancefourteenand the projecting teeth or spurs g are an even number of teethapart-via, six on one side and eight on the other. The gear-wheel F hasan even number of teeth alsoin this instance thirtywhile theratchet-wheel F keyed 0n the same shaft, has but fifteen teeth, or halfas many as there are in the wheel F. WVith this arrangement the bolt maybe tripped into action at any one of fifteen points relatively to thewheel F with its thirty teeth, and also with the pinion G, which willpass thirty teeth by a given point for each revolution of the wheel F.It will thus be seen that the bolt can only be tripped into action atfifteen out of thirty points or teeth, or at every odd tooth, so that ifthe gears are properly enmeshed and the extension-spurs g on the eventeeth the bolt cannot be tripped so as to strike upon their endsin fact,cannot be thrust into their path when they are nearer than one spaceaway from it. With this in view seven extension-spurs might be employedon the wheel-G, being half of the whole number of its teeth and each twoteeth apart.

The prime number or factor upon which this system is based must be therelative number of teeth in the wheel F and the ratchet F In this casethe wheel has thirty teeth and the ratchet fifteen, or half as many asthe wheel, so that the factor is one-half, or two teeth. Now, the numberof teeth in the wheel and also in the pinion must be divisible by twoand the extension-spurs on the pinion at least two teeth, or somemultiple thereof, apart.

An arrangement where the prime factor would be three instead. of twowould be as follows: wheel F, thirty teeth; ratchet, ten teeth pinion,fifteen teeth. In this case the ratchet would start the trip at tenpoints out of the thirty on the wheel F, or once for every three teethon said wheel, and also on the pinion, the fifteen teeth or spaces ofwhich being divided by three would permit of five extension spurs threeteeth apart each; or if a less number be employed they must be spaced atsome multiple of three. I
